HPUX 11.11 NFS client hang

Hi.

I'm having problems with my HP C8000 and 11.11 (ifs client needs to be restarted every week), trying to get it worked out.
When I searched the web it seems, I require the following patches:
PHKL_41041, PHKL_43823, PHKL_43577
Is there anyway to get hold of these packages?

Many thanks for any kind of help!

To get the patches, I you'll need a support contract with HP.

HP IT Resource Center - Hewlett Packard
us-support.external.hp.com/

otherwise, if you log in and don't have one, you'll see:

Insufficient authorization
We are sorry but you do not have the appropriate level of authorization to access Patch management.

You must have an active software updates support agreement in your HP Support Center profile in order to access Patch management.

You can add Support agreements to your HP Support Center profile by linking them to your HP Support Center user ID or by asking another HP Support Center user to share their support agreement with you. Visit My contracts and warranties for more information on linking and sharing support agreements.

If you need additional assistance please contact HP Support Center.

or, you'll need to get with someone who has a patch-bundle on CD.

on server side which your client is mounting from can try increase nfsd server threads if you have a lot of nfs clients or a lot of heavy activity. I think is under /etc/rc.config.d/nfsconf

increase to 64 or 128 or 256
